KENNEBUNKPORT, Maine (AP) – Former President George H.W. Bush is showing he has a sense of humor about falling at his Maine summer home and fracturing a bone in his neck.

The 91-year-old tweeted a smiling photo showing him in a neck brace and giving two thumbs up Thursday. He tells his followers, “Who knew jumping out of planes was safer than getting out of bed?” He also gives thanks for the “kind get-well messages” he’s received.
